How to enable SSL for SmtpClient in Web.config

Question

Is there a way to set the EnableSSL from the web.config?

I could set this property in code, but that wouldn\'t work for the Simple Mail Web Event and other classes t

Answer 1

I appears the class is sealed, so i made a manual extension. I thought i'd provide it for others here. Hope it can be of use to others.

/// 

/// OldSchool extension of SmtpNetWorkElement, since it's sealed.
/// 
public class SmtpNetworkElementEx
{
    private readonly SmtpNetworkElement m_SmtpNetWorkElement;

    /// 

    /// Initializes a new instance of the  class.
    /// 
    public SmtpNetworkElementEx()
    {
        Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("~/web.config");
        var mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;

        if (mailSettings == null)
            return;

        m_SmtpNetWorkElement = mailSettings.Smtp.Network;
    }

    public string Host { get { return m_SmtpNetWorkElement.Host; } }
    public bool DefaultCredentials { get { return m_SmtpNetWorkElement.DefaultCredentials; } }
    public string ClientDomain { get { return m_SmtpNetWorkElement.ClientDomain; } }
    public string TargetName { get { return m_SmtpNetWorkElement.TargetName; } }
    public int Port { get { return m_SmtpNetWorkElement.Port; } }
    public string UserName { get { return m_SmtpNetWorkElement.UserName; } }
    public string Password { get { return m_SmtpNetWorkElement.Password; } }
    public bool EnableSsl { get { return Convert.ToBoolean(m_SmtpNetWorkElement.ElementInformation.Properties["enableSsl"].Value); } }
}

Use this way:

var smtpSettings = new SmtpNetworkElementEx();

_smtpClient.Host = smtpSettings.Host;
_smtpClient.Port = smtpSettings.Port;
_smtpClient.EnableSsl = smtpSettings.EnableSsl;
_smtpClient.Credentials = new System.Net.NetworkCredential(smtpSettings.UserName, smtpSettings.Password);
